Application filed July 25, 1912. Serial No. 711,446.

To all whom it may concern:

Be it known that I, EDWIN A. OLLEY, of Syracuse, in the county of Onondaga, in the State of New York, have invented a certain new and useful Incandescent-Electric- Lamp Socket, of which the following is a specification.

This invention has for its object the production of a socket for electrical appliances which is particularly simple in construction, is highly durable in use, and is readily attached to a suitable support; and the invention consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figures 1 and 2 are respectively a plan and an inverted plan of one form of my socket, the contiguous portion of the support therefor being also shown. Fig. 3 is an elevation of the socket, the contiguous part of the support being shown in section. Fig. 4 is a sectional view thereof on l1ne A-A, Fig. 2.

l is a suitable support having an opening 2 therethrough, this support being here shown as the lining strip of a panel board which strip supports the pilot lights of the various circuits distributed from the panel board. However, the support may be any other suitable part.

3 is the base of the socket, the base being here shown as of greater length than width.

4 and 5 are respectively the central terminal and the outer sleeve terminal of the socket, these terminals being located in a recess 6 of greater length than width formed in the face of the base 3 opposed to one face, as the rear face, of the support 1. The central terminal 4 is mounted on a projection 40 located within the recess 6 and extending forwardly from the central part of the inner or bottom face of the recess; and the outer terminal 5 is seated directly in a slight indentation in said inner or bottom face 60, and is formed of a diameter nearly equal to the width of the recess 6. The side wall of the recess is formed by a marginal flange 7 on the front face of the base, the edge of which flange engages the rear face of the support 1.

The terminals 4, 5 are connected to wire terminals 8, 9 which extend in opposite directions therefrom to points on the bottom of the recess 6 at the outside of the vertical or lengthwise planes of diametrically opposlte side portions of the bottom end of the outer sleeve terminal 5. The intermediate portion of the wire terminal 8 inclines forwardly from its outer end along, and in contact with, the outer end surface of the project-ion 40, and the inner end of said terminal is arranged in front of the front surface of said projection and is directly engaged with the central terminal 4; and the wire terminal 9 consists of a flat bar arranged substantially parallel with the bottom face 60 of the recess 6, and having its inner end arc-shaped, Fig. l, and mounted on an inturned flange on the bottom end of the terminal 5. The outer ends of the wire terminals 8, 9 are spaced apart a distance greater than the diameter of the sleeve terminal 5 and are provided with binding devices as screws 10 to which the line wires are connected, said wires extending through cutouts or passages 11 formed in the marginal flange 7 of the base at points between the ex treme opposite end portions of the recess 6 and the flange 7 The outer terminal 5 extends through the opening 2 of the support, and is usually a screw threaded sleeve, the sleeve preferably projecting beyond the front face of the support 1.

The means ooacting with the sleeve terminal 5 to clamp the socket in position, is preferably an internally threaded collar 12 of insulation, the collar coacting with the front face of the support 1 and having a reduced portion 13 extending within the opening 2 between opposing surfaces of the sleeve 5 and the wall of said opening 2.

The socket is prevented from turning when in position and also during the turning of the collar 12 by means of a lug 14 provided on the base, the lug being adapted to enter a suitable socket 15 in the rear face of the support 1. As illustrated, the base is provided with two lugs 14: projecting from the portions of the flange 7 at the extreme ends of the recess 6.

This socket is particularly advantageous in that it can be readily secured to its support without the use of fastening means as screws piercing the support.

What I claim is:

1. A socket for an electrical appliance comprising a base arranged to engage the rear side of a support, and having its front I end engaged with the screw ring terminal,

face provided with a recess and with a marginal flange constituting the inclosing side wall of the recess, the flange having wire passages extending therethrough between opposite end portions of the flange, said base being provided with a projection extending forwardly from the bottom face of the recess, a central terminal mounted on the front face of the projection, a screw ring terminal mounted on the bottom face of the recess and adapted to extend into an opening in the support, wire terminals having their outer ends on the bottom face of the recess outside of the lengthwise planes of opposite portions of the screw ring terminal and in proximity to the wire passages, one wire terminal having its inner end engaged with the central terminal, and the other wire terminal having its inner end engaged with the screw ring terminal, and a collar turning on the screw ring terminal and coacting with the front face of the support, substantially as and for the purpose described.

2. A socket for an electrical appliance comprising a base of greater length than width arranged to engage the rear side of a support, and having its front face provided with a recess and with a marginal flange constituting the inclosing side wall of the recess, said recess being of greater length than width, and the flange having wire passages extending through end portions thereof, and said base being provided with an in dentation in its bottom face and with a projection within the recess extending forwardly from said bottom face, a central terminal mounted on the front face of the projection, a screw ring terminal seated in the indentation in the bottom face of the recess and adapted to extend into an opening in the support, and having its diameter nearly equal to the width of the recess, wire terminals having their outer ends arranged on the bottom face of the recess outside of the lengthwise planes of diametrically opposite portions of the screw ring terminal and in proximity to the wire passages, one wire terminal having its intermediate portion extended forwardly and its inner end engaged with the central terminal, and the other wire terminal being substantially parallel to said bottom face and having its inner and a collar turning on the screw ring terminal and coacting with the front face of the support, a portion of the collar being interposed between opposing surfaces of the screw ring terminal and the wall of the opening in the support, substantially as and for the purpose specified.

8. The combination with a support having an opening extending therethrough and also spaced apart sockets in its rear face; of a socket for an electrical appliance comprising a base arranged to engage the rear side of the support, and having its frontface provided with a recess and with a marginal flange constituting the inclosing side wall of the recess, the flange having wire passages extending therethrough between opposite end portions of the flange, said base being provided with a projection within the recess extending forwardly from the bottom face of the recess, and said flange being provided with forwardly extending lugs for entering the sockets in the support, a central terminal mounted on the front face of the projection, a screw ring terminal mounted on the bottom face of the recess and adapted to extend into the opening of the support, wire terminals having their outer ends arranged on the bottom face of the recess outside of the lengthwise planes of opposite portions of the screw ring terminal. and in proximity to the wire passages, one wire terminal having its inner end engaged with the central terminal, and the other wire terminal having its inner end engaged with the screw ring terminal, and a collar turning on the screw ring terminal and coacting with the front face of the support, a portion of the collar being interposed between opposing surfaces of the screw ring terminal and the wall of the opening in the support, substantially as and for the purpose set forth.

In testimony whereof, I have hereunto signed my name in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 24th day of June 1912.
